Re: [sudo-discuss] Donating a couple of things (mostly construction)

Thanks Robert, Please note the important difference between "self-drilling" and "self-tapping" screws. Self-drilling screws are for sheetmetal work, and self-tapping screws can be for wood (or metal but only if the metal has a hole already) Here is a page to show the difference: http://www.firstcallautosupply.com/self-drilling-screws-vs.-self-tapping-sc… note that there is some disagreement on this issue by people who are wrong on the internet, probably encouraged by cavalier use of the terms interchangably. I won't link to it, but the first google result comes up with an equally compelling article describing the screws by the exact opposite names. Personally, I think we should stick with calling the screws that have a drill-bit on the tip, which drill their own holes, "self-drilling" and the other screws, which are merely pointy and tap their own threads into an existing hole, "self-tapping" "Drywall screws" look like "self-tapping" screws but they have a curved chamfer under the head for some reason having to do with making drywall look nice, and they are usually black. thanks so much for everything but the beer! -jake On Mon, 2 Apr 2018, Robert Chu wrote: construction,
